TYPOGRAPHICAL COMPOSING-MACHINE.

Specification of Letters Patent.

Application filed April 15, 1912.

Patented Dec. 2, 1913.

Serial No. 690,853.

To all whom it may concern:

Be it known that I, Gnonon P.1(1NGSIBIJI1Y, a citizen of the UnitedStates, and a rcsident of Brooklyn, county of Kings, and State of NewYork, have invented a new and useful Improvement in TypographicalComposingMachines, of which the following is a specification.

My invention relates to typographical composing machines, such aslinotype ma chines of the general organization represented in LettersPatent of the United States, No. 436,582, to O. lvlergenthaler, whereincirculating matrices are released from a magazine in the order in whichtheir characters are to appear in print, and .thcn assembled in linetogether with spacers, the composed line transferred to the face of amold, the mold filled with molten metal to form a slug or linotypeagainst the matrices which produce the type or characters thereon, andthe matrices thereafter elevated and returned through a distributingmechanism to the magazine from which they started.

More particularly it relates to the matrix escapement actuating devices,as shown for instance in the Letters Patent to Morgenthaler, No.658,740, wherein a plurality of such devices is illustrated and alsomechanism whereby they are alternately actuated from a single operatingmeans.

The general object of such construction is to deliver continuouslysimilar matrices from different channels containing them, automaticallyand without demanding the care or attention of the operator, theprincipal advantage being that the more frequently employed matrices,such for instance as those representing the letter e, may thus becontinuously released without the danger of exhausting the supply, asmight be the case were they stored only in a single channel. To thisend, and in order to effect the automatic alternate operation of aplurality of escapements, I preferably employ a corresponding pluralityof actuating reeds, and in connection therewith an actuating memberformed with different portions adapted to engage the different reeds,and a single operating means for the said actuating member. In thespecific form shown, this member is a wheel which is operated from thekeyboard mechanism in the customary manner, and formed on opposite sideswith projecting pins arranged to engage alternately with a correspondingpair of reeds.

Another feature of my invention is the provision of means whereby theactuating member is first brought into position to ac tuate a reed, andby a subsequent movement is freed therefrom. In the specific formillustrated, the operating cam is formed with a cylindrical cam surface,which engages the actuating pin with the reed and permits it to dwell inthis relation until the escapement has had time to act, after which ariser on the cam operates to disengage it therefrom.

In the accompanying drawin I have shown my improvement by way of exampleand in preferred form, as applied to the specific kind of machinealready mentioned, but obviously many changes and variations may be madetherein, and similarly it may be used in connection with othertypographical composing machines, such as type-setters, type-casters,and the like, without departure from its spirit; and generally speaking,I desire it to be understood that I do not limit myself to any specificform or embodiment except in so far as such limitations are specified inthe claims.

Referring to the drawing: Figure 1. is a detached perspective view ofthe escapemcnt actuating devices, having my invention applied thereto;Fig. 2 is an enlarged transverse sectional view; and Fig. 3 is a frontdetail view.

The matrices X are as usual stored in channels of the magazine A, eachof which channels is provided with an cscapement A a pair of suchescapements being illustrated in Fig. 1. A correslmnding pair of reeds Band B serve to actuate the escapements, they being moved in onedirection by springs ll and, in the opposite direction by the ratchetwheel K. The wheel K is rotated step by step by the pawl J connected tothe longitudinally movable bar H, which is reciprocated in the wellknown manner by the pivoted arm I) carrying the cam I), and which cam isadapted to be brought into operative engagement with the constantlyrotated roll C by the finger'key G, slide G and tripping pawl F. Exceptas otherwise indicated, the several parts are or may be of the ordinaryconstructnm.

'llurning now to my improvement, it will be noted that the reeds B and Bare located at opposite sides of the ratchet wheel K, and that thelatter is formed on one side with a series of pins L adapted to' engageand actuate the reed B, and at the opposite side with pins M to engagethe reed 5 It will further be noted that the pins M and L are alternatedor staggered with relation to each other, so that they are alternatelybrought into operative relation to the respective reeds. It thereforefollows that the continued step-by-step rotation of the wheel K resultsin the alternate actuation of the es capements, and that matrices arethus alternately released from the corresponding magazine channels. Inthis manner the liability of exhaustion of any particular or frequentlyemployed matrix may be obviated. Of course, the pins L and M may bearranged in alternating groups of two or more, if desired, the effect ofsuch arrangement being the release of corresponding alternating groupsof matrices fromthe respective magazine channels.

As is well known in the art, the actuation of the escapement A involvesthe necessity for a slight dwell, in order to permit the free escape ofthe delivered matrix and the passage of another to take its place,before the parts. return to normal position. As previously indicated,the reeds B and B are moved positively in one direction by theengagement therewith of pins L or M, respectively. In order to permitthe necessary dwell referred to, the pin should remain in engagementwith the reed for a definite period, and this is provided for by theformation on the cam E of the cylindrical cam surface E It is nextnecessary to move the pin out of engagement with the reed, and this Ieffect by providing the cam E with an additional or supplementary riserE, which, on engagement with theconstantly rotated roll C, and throughthe pivoted arm D, ba v H and pawl J, moves the ratchet wheel K to itsfinal position and thus disengages the pin from the reed, and permitsthe spring B to return the reed, and consequently also the restorationof the escapement A to its normal position.

As previously stated, I have illustrated my invention by way of exampleand in preferred form, but obviously many modifications thereof willsuggest themselves to those skilled in the art and still be comprisedwithin its spirit.

Having thus described my invention, its construction and mode ofoperation, what I Copies of this patent may be obtained for five centseach, by addressing the Commissioner of Patents,-

claim and desire to secure by Letters Patent of the United States is asfollows:

1. In a typographical composing machine, the combination of a pair ofescapements for the type or matrices, a corresponding pair of reeds toactuate the said escapements, and a periodically operated singleactuating means for the said reeds, the said actuating means beingformed with different members to engage the different reeds and solocated that the reeds are engaged alternately thereby.

2. In a typographical composing machine,

the combination of a pair of escapements for the type or matrices, acorresponding pair of reeds to actuate the said escapements, andaperiodically rotated member formed with projecting portions arranged instaggered relation so as to engage the reeds alternately.

3. In a typographical composing machine, the combination of a pair ofescapements for the type or matrices, a corresponding pair of reeds toactuate the said escapements, and a periodically rotated wheel formedwith portions projecting from its opposite sides to engage the reedsalternately.

4. In a typographical composing machine, the combination of a pair ofescapements A a pair of actuating reeds B, B, and the periodicallyrotated wheel K formed with the oppositely located pins L and M toengage the reeds B andB respectively.

5. In a typographical composing machine, the escapement actuatingmechanism comprising in combination, the reed, the wheel having anactuating portion to engage the reed, and an operating cam and suitableconnections to rotate the wheel, the said cam being so formed as tobring the actuating portion into engagement with the reed, then topermit a dwell, and then to move the actuating portion out of engagementwith the reed,

6. In a typographical composing machine, the escapement actuatingmechanism comprising in combination, the reed B, the wheel K having thepin L, and means to rotate the wheel K, comprising the cam E having thecylindrical portion E and the riser E In testimony whereof I hereuntoset my hand this 11th day of April, 1912, in the presence of twoattesting witneses.
